Early life and education edit

Periasamy was born in India. He trained at the University of Madras and the Indian Institutes of Technology.[1] After earning his doctorate in 1984, Periasamy moved to the University of Washington for a postdoctoral research position.[1]

Research and career edit

Periasamy founded the W. M. Keck Centre for Cellular Imaging. His research considers the development of microscopy for imaging of living cells. He has designed various advanced modalities, including multi-photon and confocal approaches. In particular, Periasamy is interested in understanding protein-protein interactions and the monitoring of physical parameters in cancer cells.[2] Periasamy was one of the first researchers to demonstrate fluorescence-lifetime imaging microscopy (FLIM) and fluorescence lifetime redox ratio (FLIRR).[3][4][5]
